UNITED YSTATES PATENT OFFICE;

JOSEPH T. ROBBINS, OF NEVTON, IOVA.

STOVE OR FU RNACE.

SPECIFICATION forming part of Letters Patent No. 418,226, dated December 31, 1889.

i Application led September 10, 1888. Serial No. 285,074. (No model.)

To all whom, it mag/concerns Be it known that I, JOSEPH T. ROBBINS, a citizen of the United States ot America, and a resident of Newton, in the county of Jasper and State of Iowa, have invented new and useful Improvements in Stoves or Furnaces, of which the followingis a specification.

My invention relates tothe stove or f urn ace for which United States Letters Patent N o. 366,255 were issued to me July 12, 1887; and it consists, first, in the construction and coinbination of an auxiliary cylinder within the chamber under the grate; second, in combining an open-ended tube with the auxiliary cylinder and stove to-1naintain an equalized temperature within a room; third, in the construction and arrangement of a water-reservoir, a double wall, and two doors, with the top, for the purpose of distributing` vapor and hot air to the iire to promote combustion and to prevent the escape of gas while the doors are open.

Figure 1 of the accompanying drawings is a vertical sectional view of one of my improved stoves. Fig. 2 is a sectional. view through the line x of Fig.V l.. Fig. 3 is a view looking down upon the base frointhe point of elevation indicated by line zz in Fig. l.

A is an open-ended auxiliary cylinder that extends horizontally through the lower cylinder B, and is frxed'to the edges of correspending` openings in the cylinder in such a manner that the products of combustion will be on the outside' of the wall. of the auxiliary cylinder and cold air admitted from outside of the cylinder to 'the inside of Fthe radiator.

C represents an ornamental filigree fixed in the open ends of the yradiator A.

D is a tube formed on or fixed to the central portion of the auxiliary cylinder to extend outward through an, opening in the eylinder B and into an openended tube F, that' extends vertically through the base G iu such a manner that the products of combustion will envelop the lower end of the tube to aid in heating cold air that enters its bottom.

H is a U-shaped open-ended radiator comJ bined with the base G at its lower end and with the double-walled top of the stove at its upper end by means of tubes 1 and 2 to carry ott odors and gases escaping from the fuel in the chamber J, and also in such a manner that the products of combustion can be circulated around the annular deliector K in jthe base G at pleasure by simply adjusting :the damper L in the top of the tube D.

(Shown in Fig. 2.)

through the cylinder B and around the auxliary cylinder A and then through an openended tube n, that is fixed in the cylinder B and the tube Il to establish communication between them.

P is a jacket fixed around the top portion ofthe fuelechamber J, and P2 is a doorway for introducing fuel.

r is a door hinged to the jacket to swinw inward and upward, as indicatedby dotted lines in Fig. l, so that it will be automatically closed by force of gravity.

a" is a rod hinged to the lower part of the door r to serve as a means for opening and propping the door open.

lr" is an open-ended tube that extends through the double wall of the top. It is provided with a damper to close the inner end thereof whenever desired, and it has perforations that will allow air to pass from the outside of the top to the space between the wall of the fuel-chamber J and the jacket P, and from thence down to the combustionchamber under the grate.

3 is a water-reserv0ir iixed in the top of the fuel-chamber, so that the vapor generated therein and escaping therefrom through the opening in its top Will mingle with the air between the jacket P and the fuel-chamber J- and pass down therewith to aid in combustion. j

The tube No. 1 connects the fuel-cha1nber with the tube H in such a manner that odors or gases in the fuel-chamber will be carried off direct int-o the escape iiue or pipe that is connected with the top of the tube H when the damper in the tube is open.

The No. 2 tube, that connects the jacket P with the tube H, will carry oft gas and offensive odor from the inside of the jacket P when ever the damper in the tube is open.

promoting IOO ' cause the gases to descend through the grate at the bottom of the fuel to aid in promoting combustion.

An auxiliary grate located over the ash-pan in the bottom of the stove will prevent pieces of fuel from getting into the ash-pan and will retain them in position, Where they will continue to burn and to be consumed as required toprevent Waste of fuel.

I claim as my invention 1. An open-ended auxiliary cylinder having an open-ended branch extending'l laterally, in combination with a cylinder in a stove and an open-ended tube outside of said cylinder for the purposes of heating and circulating air in a building.

2. The auxiliary cylinderA, having abranch D, in combination with a cylinder B and a tube F, substantially as shown and described;

for the purposes stated.

3. The combination of the auxiliary cylinderA, having a branchD, and the open-ended tube F with the cylinder B and the base G, to operate in the manner set forth, for the purposes stated.

4. The combination of the jacket P, having a doorway P2 and a hinged door o", with the fuel-chamber J and the reservoir s, to operate in the manner set forth.

5. The grate-support m, having radial projections extending downward and outward to engage the top portion of thev cylinder B, in combination with a fuel-chamber J, having an open bottom to allow fuel therein to rest upon a grate placed upon the support fm, for the purposes stated.
